Ernie Ball releases versatile Expression Tremolo pedal
Latest Expression pedal packs Harmonic mode and built-in reverb
First revealed back at NAMM, Ernie Ball’s Expression Tremolo pedal is now officially available in the USA, with the international launch taking place in September.
The Ernie Ball Expression Tremolo pedal offers five waveforms (slow rise, slow fall, sine, square and harmonic), with depth, rate or both adjustable via its onboard treadle.
There’s also a control to adjust a built-in spring reverb, which is controlled via the treadle, too.

The Expression Tremolo is available now in the USA for $199, while it will sell for £199 when it lands in the UK and the rest of the world in September.
